NEMA17 Snapfit 40x40 Fan Mount for Prusa

thingiverse

To address the overheating issue of NEMA17 steppers at around 50°C, consider installing 40x40x10 fans for a reduction of approximately 5°C. Ensure your stepper has recessed corners for snapfits; the fan purchased has 2.8mm holes requiring M2.5 fastenings. Assemble with two M2.5x12 screws and nuts, and expect some finishing touches on the printed part due to clearance in the snapfit. The lightweight design (3.2g) prints within 26 minutes.
